"This market is interesting to walk around although quite a lot of repetition in the stalls and products. Incredibly crowded but it was approaching Tet when we visited. The market is only running on the weekend Fri,Sat & Sun nights so plan around these if you want to visit. Even if you visit this area on a non-market night there are lots of shops open selling a range of things around the streets to look in".

Night Market Hanoi

The Night Market - is almost entirely in Southeast Asia a well known phenomenon. It is always a pleasant with a lot of people and stalls where you can buy everything. Hanoi is no exception to that.
The Hanoi Night Market is three kilometres long and extends from the Hang Dao Street fountain in the northern part of Hoan Kiem Lake to Dong Xuan Market (the Old Quarter).

During the day the street is normally used for traffic. Tourists walk in the street to go downtown or to the Old Quarter and the
cargo's are delivered by road to the shops.
But in the evening it is off limits to all means of transport. The street is the domain of the sellers. Stalls are put down and the goods are displayed. It is the place where you can negotiate about the price of your chosen product.
Formerly the night market was only in the Old Quarter, but the government has recognized that there had to be an official night market in Hanoi and expanded it. Please note that this night market is not held every evening. It's only held the weekend: Friday, Saturday and Sunday.

Dinner at the Night Market

The night market usually starts at 18:00 and closes at 23:00. Only on Saturday you can buy a souvenirs or something else. Then there are also other activities such as musical performances, lion dance and other cultural performances.
These will be held in the near Hoan Kiem Lake.
Every night of the weekend some 2,000 stalls are displayed, mainly garments, textiles and other souvenirs for tourists. You can also enjoy exotic rice dishes, which are sold. These stalls you find mostly in the Old Quarter.

Night Market

From a travel blog:

"Hanoi night market is a good choice of a weekend for street food. Between Friday
evening and Sunday evening the local roads are closed to allow for the street stalls to set up. Great atmosphere, locals and
tourists visit to enjoy shopping, food, drink and music. Lots of street food to be tried but most of the stalls sell similar products (same same). Fake branded goods a plenty, souvenirs, clothing etc...."
